Rocket Fin Can for 29mm body tube

thingiverse

I have flown this model numerous times above the speed of sound, every time without incident thanks to perfectly aligned fins. All it takes is a print at normal speed with 10% fill, including rafts, and epoxying the fin can just a quarter inch above a 12-inch body tube that fits perfectly with Blue Tube tubes, adding a golf ball to the top for stability, secured with duct tape on top of the motor retention ring. Excess epoxy helps seal in smooth fins with extra strength by filling the fin fillets and launch rod lugs. After only five minutes preparation time using single use Aerotech motors such as the H135 or H195 to go supersonic and without a Level 1 Certification required, the model is ready to take flight; users without certifications may use G-motors safely.
